What can be the cause of and treatment for cervical adenopathy?

Cervical lymphadenopathy refers to swollen lymph nodes in the neck. Lymph nodes commonly enlarge in response to an infection. In the neck, causes include strep throat, an ear infection, a viral infection like mononucleosis (“mono”), or a skin infection. Rarely, an enlarged lymph node in the neck can signal a more serious problem, such as lymphoma or other cancer. Quite often neck lymph nodes swell for a couple weeks and then shrink in someone who feels well and no reason is found.
